Blow-by gases can mix with oil vapors in your crankcase, contaminating your oil and creating sludge. Your positive crankcase ventilation (PCV) system gets those gases out, recirculating them for combustion. The system may need a source of fresh air, preferably free of dirt and debris—that’s where the valve cover breather comes in!

Top Brands

From plain Jane to shiny and show-ready, Summit Racing Equipment carries an amazing selection of valve cover breathers. Shop from manufacturers like K&N, Proform, Billet Specialties, Cal Custom, Spectre, Moroso, and many more.
